~10 degree difference between upstairs and downstairs rooms
I live in a 2 story single family ~1700 sq foot home where there is an uncomfortable 10 degree difference between the floors in the winter (too cold upstairs) and the summer (hot as hell upstairs).
We have a single thermostat on the main floor. Setting it to 72 in the winter leaves the upstairs around 65 and a sole bedroom in the front corner of our house is a few degrees cooler than that. That bedroom is what I need to address and it only has a single duct running to it. The temp slowly drops as the night goes on, leaving it quite chilly the next morning.
Attic currently has a low R-19 level.
I am considering a few options but its very difficult to navigate.
1. Identify leakage points in the attic (and house overall) and address plus add insulation in attic to minimum R-49
2. Install dampers for a multi-zone setup so the upstairs bedroom can continue to get heat (worried about a bypass being installed)
I am assuming that option 2 will no doubt keep the bedrooms (and other zones) comfortable since the desired temp should be reached, but should I also insulate so any leakage and heat transfer can be slowed to reduce system usage?
Which one should I “try” first?
